Power ultrasonic transducers with extensive radiators for industrial processing.

Area of Science:

• Engineering
• Materials Science
• Acoustics

Background:

• High-power ultrasonics (HPU) is a green technology with vast industrial potential.
• Limited commercial applications exist due to a lack of suitable large-scale transducers.
• Existing transducers often lack the power capacity, efficiency, and adaptability for diverse industrial needs.

Purpose of the Study:

• Introduce a new family of HPU transducers with extensive radiators.
• Address limitations in power capacity, efficiency, and radiation pattern control.
• Facilitate broader industrial adoption of HPU technology.

Main Methods:

• Design and development of HPU transducers with adapted radiators for specific applications.
• Incorporation of strategies to mitigate nonlinear behavior and modal interactions.
• Evaluation of transducer performance in fluid and multi-phase media.

Main Results:

• New HPU transducers offer high power capacity, high efficiency, and controlled radiation patterns.
• Designs effectively reduce modal interactions common in high-power operation.
• Successful implementation in semi-industrial and industrial processes across various sectors.

Conclusions:

• The new HPU transducers overcome previous limitations for large-scale applications.
• These advancements are driving the development of HPU in food, environmental, and manufacturing industries.
• The characterized transducers represent a significant step towards broader HPU industrial integration.
